GraphSight Junior is an easy to use freeware handy 2D mathgraphing program. It was originally designed to help students and teachers satisfy their dayafterday math plotting needs. It makes it easy to plot and explore common Y(X) = F(X) Cartesian graphs, set text labels on the coordinate plane, zoom or shift a graph with just a single click & move of mouse. The resulting picture can be than exported to a file or windows clipboard as a bitmap.
Originally GraphSight has come as a realization of the idea "A graph does not have to be dead!". This is gained through the interactivity of every graph on a coordinate plane. All of them react to mouse or keyboard input, each of them have its own shortcut menu, remembers all the formulas you enter for it, can be displayed using different styles, colors and sizes and much more.

Are you an engineer, scientist or graduate student looking for a graphing tool that will allow you to quickly analyze graphed data without having to immerse yourself into calculus and statistics books? You've just found the perfect solution. FindGraph is a comprehensive, featurerich graphing, digitizing and curve fitting software specially created for these purposes. Take any graph or data from any source (Web or PDF document, for example) add your comments and perform any manipulations, like building approximation lines. Then print your results or export them to Excel or other database. The program comes with a straightforward interface, 200 builtin common graphing functions (like Cardioid, Devil's Curve, or Double Folium), support for Polar, Cartesian, and Parametric equations, various data input/export features and printing options.
Builtin Wizard of Digitization will help you to digitize the data. One of the major features FindGraph provides is an easy way to do curve fitting. The program offers 10 generic fits, including Linear Regression, Logistic Functions, Fourier approximation, Neural Networks plus a library of over 120 industryspecific formulas. Builtin Wizard of Approximation helps applying different curve fits to discover the model that describes data the best. The software also enables users to smooth, subtract, differentiate, integrate, and transform data and curves.
Most importantly, FindGraph provides an easy way to copy and paste (embed) graphs to other software applications, like word processors, MS Excel or image editors. Moreover, the program supports OLE automation and can be builtin to other software applications. Best of all, FindGraph is free to try. You can test the software at no charge for the entire length of trial period  30 Days! If you have any questions about implementing the software in your classroom or want to inquire about special low prices for academic institutions, don't hesitate to contact us.

3D Grapher is a featurerich yet easytouse graph plotting and data visualization software suitable for students, engineers and everybody who needs to work with 2D and 3D graphs. 3D Grapher is small, fast, flexible, and reliable. It offers much of the functionality of heavyweight data analysis and graphing software packages for a small fraction of their cost. The program is very easy to learn  you don't need to read long manuals to figure out how it works, but can just play with 3D Grapher for several minutes and start working.
3D Grapher provides for three systems of coordinates: Cartesian, cylindrical and spherical. Graphs can be generated from table data or from the manually entered equations. You can specify the unlimited number of equations and tables and their graphs will be plotted in one coordinate system using different colors and lighting conditions. This feature helps you visualize and analyze the domains and intercepts of several functions.
Functions can be parametric, and can include a time variable  this feature allows creation of animated graphs and models. You can easily rotate the created graphs with the mouse, zoom them and view at any angle. Other program features include:
1) Builtin expression calculator
2) Mouse cursor coordinate tracking
3) Fully customizable userfriendly interface for highly efficient workflow
4) Ability to import and export data in several popular file formats
5) Ability to copy the graphs and paste them into your own documents
6) Support for OpenGL video accelerators.

Don't spent hours writing a program for some programmable calculator while MtrxCal can perform the same calculations with just a few simple lines. Don't waste time trying to find the right maximum and minimum values for plotting your functions. Just let MtrxCal use its buildin autoscaling feature. The syntax for adding two values and adding two matrices containing hundreds of values is the same. Define a range like x=[6:0.1:6] and calculate the sinus of this matrix like y=sin(x). Now you can just plot all the values with the command plot(y) or plot the power of y using the command plot(y.^2)

RF21 for Windows is a scientific calculator, plotter, programming and numeric system in one. It allows for permanent installation of a user's own commented functions and libraries. Such user functions may have one or several arguments and values. Works as an archive at the same time, with integrated searchable database, to let you find and reuse materials created years ago. Each function selfreassembles when its name is called, autonomously searching the libraries for all components needed.
Predefined functions include gamma, zeta, psi and Bessel functions, error integral, cumulative Binomial distribution and more. On top of these and the user libraries, the program's numeric and plotting capabilities can be used, including:
Numeric derivation and integration, Monte Carlo simulations, linear equations, matrix inversion and eigenvalues, nonlinear equation systems, ndimensional function minimizer (Dennis & Schnabel method), Runge Kutta method for (systems of) differential equations, accelerated summation of series. Fraction reckognizer.
Fast screenplots and an environment for designing printable plots, which may as well be exported to .GIF and .BMP files. Ample support for both simple and parametric plots, composition of several curves into one picture, drawing of directional or vector fields.
Comes with standard libraries covering areas of science and mathematics. Some 200 standard functions, see author's homepage for a systematic reference of these.
